Product type
MAP packaging, or Modified Atmosphere Packaging, is a technique used to extend the shelf life of perishable food products by altering the composition of the internal atmosphere of the packaging. Typically, this involves replacing the air inside the package with a mixture of gases such as carbon dioxide, nitrogen, and oxygen. This method helps to slow down the growth of bacteria and mold, preserving the freshness and quality of the food.
| Material | Polyethylene, polypropylene, or multi-layer films |
| Gas composition | Typically 30-80% nitrogen, 20-70% carbon dioxide, and 0-21% oxygen |
| Seal type | Heat seal or peelable seal |
| Temperature resistance | Suitable for refrigeration and freezing applications |
| Shelf life extension | Can extend shelf life by 2 to 5 times depending on product |
When selecting MAP packaging, consider the type of food product and its specific storage requirements. Specify the desired gas composition based on the product's needs, as well as the required material and thickness of the packaging film. Additionally, inquire about any relevant certifications for food safety and compliance with industry standards. Quantities can vary based on production needs, so it’s advisable to discuss bulk purchasing options.
